TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 328,761, dated October20,1885.

Application filed September 10, 1885. Serial No. 176,684. (No model.)

To all whom t may concern,.-

Be it known that I, J. H. CILLEY, a citizen of the United States,residing at Lebanon, in the county of Lebanon and State of Pennsylvania,have invented certain new and useful Improvements in Tricycles; and I dohereby declare the following to be a full, clear, and exact descriptionofthe invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an attachment for tricycles, whereby theordinary tricycle of the front-steering77 class may be converted into atandem velocipede to carry two riders.

The attachment consists of a frame, which, in the present instance, toillustrate my invention, is an exact counterpart of that which projectsforward from the axle of the Columbia tricycle, and is provided with awheel, pedal-crank axle, saddle, and handlebars. The frame is providedwith side bars, having on their ends clips for attaching it to the axleof the tricycle and for forming a vertical joint to allow the frame torise and fall to compensate for any irregularities in the road.

In the accompanying drawings,which form a part of this specification,Figure 1 represents a side View of a Columbia tricycle provided With myattachment; Fig. 2,a rear view of the same; Fig. 3,a side View of theattachment detached from the tricycle; Fig. 4, a side view of thespring-clip and a section of the ball-bearing case on the axle, Fig'.5,a top View of the same; and Figs. 6 and 7 represent details of theconstruction of the steeringrod and its slide-bearing.

Reference being had to the drawings and the letters of reference markedthereon, A represents the frame of a tricycle to which the attachment isconnected. The construction of this part of the machine being well knownit will require only a general description of such parts as arenecessary to understand my invention. a is the ax1e,upon which aremounted the driving-wheels b b; c, the small steeringwheel; d, the seat;e, the pedal-crank axle, f, the steering-handle, g, the driving-gear.

B represents the attachment for forming the tandem velocipede. c a arethe side bars of the frame, upon the ends of which are formedspring-clips b b', which, in the present instance, are adapted to iitover and engage with the ball-bearing case c of the main axle a. d isthe swinging-latch of the clip, connected to the frames afa at e', andadapted when thrown into contact with the spring-clip to engagetherewith by the former passing through the slot f, formed in the latch,as shown in Figs. 3, 4, and 5.

The frame or attachment is provided with a wheel, C, a pedal-crank axle,D, a saddle, E, and handles F F, which correspond with those on the mainmachine. The seat or saddle E is adjustably supported upon an archedportion, G, rising vertically from the side bars, a a', of the frame.The arch or seat-support is braced to the rear portion-of the frame, asshown at i z'.

A foot-rest, H, is secured between the forward ends of the side bars forthe accommodation of the rear rider when not operating the pedal-crankaxle of the attachment. The frame of the attachment is of the samelength and width as the main frame, and the front and rea-r wheels aretherefore equidistant from the main axle. By this construction themachine is perfectly balanced and causes it to run evenly and smoothlywithout the jar which is incident to 'the single machine. The front andrear frames being of the same width the machine becomes a three-trackmachine,77 as the rear wheel follows in the same track as the frontwheel.

Upon the main axle is permanently attached an additional driving orsprocket wheel, I, over which is passed a chain having a removable bolt(not shown) connecting the links at one point to provide for its beingseparated to attach it to the wheel I on the main axle and the wheel Jon the pedal-crank axle D of the auxiliary frame.

The machine is steered wholly by the front rider 5 and to this end thefront and rear wheels are connected by a rod, K K, which is attached toa lug, k, on the rod Z, leading from the arm m of the front wheel to thesteeringhandle f. Io the inside of the main frame and the safety-stay issecured a guideway, n, in which is placed a slide, o, from whichprojects a stud or pin, p, upon which the inner ends of the rods aresecured by a suitable washer,

thus forming a joint in the rod K K, which accommodates itself to anyirregularities in the road, such as deep gutters or gullies, in crossingwhich the front and rear parts of the machine are thrown ont of the samehorizontal plane. By connecting the front and rear wheels they arealways under. the control .of the front rider, and are made to trailvery accurately by reason of the rear wheel, C, having its steering armor lever` q project from the opposite side of the wheel as compared withthe wheel c and its arm m, and, that they are equidistant from the mainaxle, thus enabling the machine to be turnedA in a very small space.

Upon reference to Figs. 4 and 5, it willbev observed that the sidebars,ya. a', of theframe. areiiattened at vtheir ends and1 slightly bent, tofacilitate the connection with the ball-bear;-

ing case, and that .by connectingv the fralnexto the saidl case noadditional friction is incurred.

Another advantage of my construction is` that .v the tension of the reardriving-chain-` is. not affected by any of the irregularities intheroad, as the vertical joint formed by attaching therear frame to theball-bearing case onv the mainaaxle allows .the entire frame to swingVfreely without 4 in any manner changing. the tension of the drive-chainconnecting themearv pedal-crank axle with the mainv axle.

The front and rear frames being connected. togetherby their attachmentto the main axle in the same vertical plane form a-yery. stiff andsubstantial machine, and in climbing hills are` found to balance `cachother perfectly, thus enabling both riders to 'workv ontheir re-kspective pedal-crank axles without dangerfof tilting 4either end. f:

The4 crankaxles are set at different angles,

as ,shown ,in Figs. 1 and 2, thus always prof. l

viding against the machine being upon a dead- ,cente`r, i or one `riderworking against the other,l

and presenting a ready means for starting the machine from any'positionin Awhich it mayuhave been stopped.

I would `have it understoodIthat my inventionis not limited in itsapplicationto. the style of tricycle to which itis shown attached;`- butthat it is` susceptible of changes to adapt it to different styles,which are mere mechanical expedients, and are held to be within the,v l

spirit and scope of my invention.

I am aware that tricycles haveheretofore.,

been provided with parts for converting them into tandem velocipedes,and do not, therefore, claim such anl attachment, broadly; but,

Having fully described my invention, what I claim is- 1. An attachmentfor tricycles,consisting of a frame.providedwithicontinuous side barshaving their ends formed 4into clips for at-` taching them to the mainaxle, substantially as setforth.

2. An attachment for tricycles, consisting of an auxiliary frame,provided with side bars having clips formed on their ends, incombination with the ballbearing cases on the main axle, substantiallyas described.

8. An attachment: for tricycles,consisting of an ,auxiliary frame,provided with ,side bars having their end s `reduced ,and formed lintosp ringV-clips, substantially-as described.

4. A11V attachment for tricycles,consisting of an auxiliary frame havingside barslandfan arched seat-support connecting said bars, substantiallyas described.

5. An attachment for tricycles, consisting of A an auxiliary framehaving side bars, an'arched seat-.support connecting saidbars, and afootrest, substantially'. as described.

6. A velocipedehaving a iixed anda swinging frame,l ltwo driving-wheels,a frontand rear steeringwheel, and, a `suitable.steering deviceLconnecting, said .steering-wheels, substantially as described.. t
